Description

Technical Field

[0001] The utility model relates to the technical field of wire harness assemblies, in particular to an instrument panel wire harness assembly that prevents falling off. Background Technique

[0002] The instrument panel wire harness assembly is an important part of the automotive electrical system. It is usually composed of wires, cables and connectors, and mainly plays a key role in connecting and transmitting electricity and signals. Just like the neural network of the human body, it closely connects various electrical devices with the vehicle's control unit. The material and specifications of the wires are carefully selected to ensure good electrical conductivity and durability.

[0003] At present, the wire harness assembly and the instrument panel are usually connected through plugs and sockets. This connection method is easy to install and disassemble, facilitating operations during maintenance or component replacement. However, due to the continuous vibrations generated by road bumps and engine operation during vehicle driving, the connection between the plug and the wire will be frequently bent. The connection between the root of the plug and the wire is a region where the rigid structure transitions to the flexible structure, and this structural mutation easily leads to stress concentration, thus increasing the risk of breakage and detachment of the connection between the wire and the plug. Content of the Utility Model

[0004] The purpose of the utility model is to provide an instrument panel wire harness assembly that prevents falling off, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an instrument panel wire harness assembly that prevents falling off, including: a support frame, a plug is fixedly installed on the inner wall of the support frame, and a wire is arranged at the connection end of the plug. An adjusting frame A is hinged between the inner walls of two ends of the support frame, and an adjusting frame B is hinged between the inner walls of the other two ends of the support frame. Two arc-shaped grooves are symmetrically opened on the inner walls of the adjusting frame B and the adjusting frame A. Two groups of limiting grooves are symmetrically opened on the inner sides of the two arc-shaped grooves. Memory springs are fixedly connected to one ends of the inner sides of the limiting grooves, and hinge seats are fixedly connected to one ends of the memory springs. The outer walls of the hinge seats are slidably connected to the inner walls of the limiting grooves.

[0006] Preferably, clamping components are arranged on the inner sides of the arc-shaped grooves. The clamping components include connecting pipes, and the outer sides of the connecting pipes are slidably connected to the inner sides of the arc-shaped grooves. One end of the connecting pipe is rotatably connected to a rotating block. A threaded adjusting rod is threadedly connected to the inner wall of the rotating block, and the outer side of the threaded adjusting rod is slidably connected to the inner wall of the connecting pipe. A clamping seat is fixedly connected to one end of the threaded adjusting rod, and two limiting columns are symmetrically and fixedly connected to the outer side of the clamping seat.

[0007] Preferably, two limiting blocks are symmetrically and fixedly connected to the outer wall of the connecting pipe, and the outer sides of the plurality of limiting blocks are respectively attached to the outer sides of the adjusting frame A and the adjusting frame B.

[0008] Preferably, the outer walls of every two limiting columns are slidably connected to the inner wall of a limiting block.

[0009] Preferably, hinge frames are symmetrically and fixedly connected between the outer walls of every two limiting blocks, and both ends of the hinge frames are respectively hinged to the inner walls of two hinge seats.

[0010] Preferably, every two clamping seats are symmetrical, and the inner sides of the clamping seats are attached to the wire.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the wire shakes and bends towards any direction, one of the memory springs will be compressed under force, while the other memory spring will be stretched under traction. In this way, the reaction force generated by the memory spring when it is stressed provides a certain elastic support for the wire, reducing the bending amplitude of the wire, thereby reducing the concentration of stress in the transition area between the rigid and flexible structures, avoiding excessive pressure on the local area, and further reducing the risk of breakage and detachment at the connection between the wire and the plug.

[0013] 2. By rotating every two opposite rotating blocks, the inner wall of the rotating block is in threaded cooperation with the outer wall of the threaded adjusting rod, so that the threaded adjusting rod can push the inner clamping seat through the inside of the connecting pipe to clamp and support the wire. In this way, the clamping and support of the wire by the clamping seat increases the support points at the connection between the plug and the wire, avoids excessive stress concentration at a certain point when the wire shakes, and then reduces the stress concentration degree and the burden at the connection between the plug and the wire, thereby further reducing the risk of breakage and detachment between the wire and the plug due to stress concentration during frequent bending and shaking of the wire.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown in

[0025] In this implementation scheme, first, by adjusting the hinges between the adjusting frame A4 and the adjusting frame B5 and the support frame 1, and the arc-shaped grooves 6 provided inside the adjusting frame A4 and the adjusting frame B5, the connecting pipe 101 has a certain amount of movement space and the movement trajectory of the connecting pipe 101 is limited. Secondly, due to the tension of the memory spring 8, the hinge seat 9 supports the connecting pipe 101 through the hinge frame 12. Then, the wire 3 is clamped and supported by the clamping seat 104. When the wire 3 shakes and bends towards any direction, one of the memory springs 8 will be compressed under force, while the other memory spring 8 will be stretched under traction force. In this way, the reaction force generated by the memory spring 8 when it is stressed provides a certain amount of elastic support for the wire 3, reducing the amplitude of the wire 3 when it bends, thereby reducing the concentration of stress in the transition area between the rigid and flexible structures, avoiding excessive pressure on the local area, and further reducing the risk of breakage and detachment at the connection between the wire 3 and the plug 2.

[0026] As Figure 2 and Figure 4 shown, clamping components 10 are provided on the inner sides of the arc-shaped grooves 6. The clamping components 10 include a connecting pipe 101, and the outer side of the connecting pipe 101 is slidably connected to the inner side of the arc-shaped groove 6. One end of the connecting pipe 101 is rotatably connected to a rotating block 102. The inner wall of the rotating block 102 is threadedly connected to a threaded adjusting rod 103, and the outer side of the threaded adjusting rod 103 is slidably connected to the inner wall of the connecting pipe 101. One end of the threaded adjusting rod 103 is fixedly connected to a clamping seat 104, and two limiting columns 105 are symmetrically and fixedly connected to the outer side of each clamping seat 104; each pair of clamping seats 104 is in a symmetrical state, and the inner sides of the clamping seats 104 are in contact with the wire 3.

[0027] In this implementation scheme, by rotating each pair of opposite rotating blocks 102, the inner wall of the rotating block 102 is in threaded engagement with the outer wall of the threaded adjusting rod 103, so that the threaded adjusting rod 103 can push the clamping seat 104 through the inner wall of the connecting pipe 101. Since each pair of clamping seats 104 is in a symmetrical state, by rotating two opposite rotating blocks 102, the two clamping seats 104 can clamp and support the wire 3. In this way, the clamping and support of the wire 3 by the clamping seat 104 increases the support points at the connection between the plug 2 and the wire 3, avoiding excessive stress concentration at a certain point when the wire 3 shakes, thereby reducing the stress concentration degree and the burden at the connection between the plug 2 and the wire 3, and further reducing the risk of breakage and detachment between the wire 3 and the plug 2 due to stress concentration during frequent bending and shaking of the wire 3.

[0028] As Figure 4 and Figure 6As shown in the figure, two limiting blocks 11 are symmetrically and fixedly connected to the outer wall of the connecting pipe 101, and the outer sides of the plurality of limiting blocks 11 are respectively in contact with the outer sides of the adjusting frame A4 and the adjusting frame B5; the outer walls of every two limiting columns 105 are slidably connected to the inner walls of one limiting block 11.

[0029] In this embodiment, the limiting block 11 is provided to ensure the stability of the connecting pipe 101 when sliding inside the arc-shaped groove 6, preventing the connecting pipe 101 from detaching from the arc-shaped groove 6. The limiting column 105 is provided to limit the clamping seat 104, so that the clamping seat 104 can restrict the rotation of the threaded adjusting rod 103, so that the rotating block 102 can be in threaded cooperation with the threaded adjusting rod 103, and when the rotating block 102 rotates, the threaded adjusting rod 103 can push the clamping seat 104 to clamp the wire 3.

[0030] In summary, the working principle of the present utility model is as follows:

[0031] First, by rotating every two opposite rotating blocks 102, the inner wall of the rotating block 102 is in threaded cooperation with the outer wall of the threaded adjusting rod 103, so that the threaded adjusting rod 103 can push the clamping seat 104 through the inner wall of the connecting pipe 101. Since the two clamping seats 104 are symmetrically arranged, by rotating two opposite rotating blocks 102, the two clamping seats 104 can clamp and support the wire 3. In this way, the clamping and support of the wire 3 by the clamping seat 104 increases the support points at the connection between the plug 2 and the wire 3, avoiding the stress from being overly concentrated at a certain point when the wire 3 shakes, thereby reducing the stress concentration degree and the burden at the connection between the plug 2 and the wire 3, and thus reducing the risk of the wire 3 breaking and falling off from the plug 2 due to stress concentration during frequent bending and shaking. Subsequently, through the hinges between the adjusting frame A4 and the adjusting frame B5 and the support frame 1, and the arc-shaped grooves 6 provided inside the adjusting frame A4 and the adjusting frame B5, the connecting pipe 101 has a certain amount of movement space and the movement trajectory of the connecting pipe 101 is limited. Secondly, due to the tension of the memory spring 8, the hinge seat 9 supports the connecting pipe 101 through the hinge frame 12. Then, through the clamping and support of the wire 3 by the clamping seat 104, when the wire 3 shakes and bends towards any direction, one of the memory springs 8 will be compressed under force, and the other memory spring 8 will be stretched under force. In this way, the reaction force generated by the memory spring 8 when it is stressed provides a certain amount of elastic support for the wire 3, reducing the bending amplitude of the wire 3, thereby reducing the stress concentration in the transition region between the rigid and flexible structures, avoiding excessive pressure on the local area, and further reducing the risk of the wire 3 breaking and falling off at the connection with the plug 2.

[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
